Title: Method of and apparatus for measuring mechanical impedance
IPC: G01H15/00
Filed: 1928-03-30
Abstract: 314,575. Beatty, W. E., (Bell Telephone Laboratories, Inc.). March 30, 1928. Vibrations, indicating, recording, and registering.-The " mechanical impedance" of a piece of apparatus is measured at a predetermined frequency by means of a Wheatstone bridge having two arms comprising equal resistances 10, 12, Fig. 1, a third arm comprising a coil 16 arranged to be mechanically coupled to the apparatus to be tested, and a fourth arm including a variable resistace 13, a fixed resistance 14, and an inductance 15 having an impedance frequency characteristic the same as that of the coil 16 when stationary. The coil 16 is mounted, as shown in Figs. 3 and 4, in the centre of the field of an electromagnet 47 by means of three tension members 19, 20, 21, of piano wire spaced 120‹ apart and silver soldered to a central steel disc 24, which carries a driving pin 25 to which the apparatus to be tested may be attached. The other ends of the tension members are fastened to the short arms of levers 26, 27, 28, resting on knife-edges 29, 30, 31. The long ends of these levers are pulled inwards by stranded wires 32 wound on a drum 35 carried by a shaft 36. Friction pins 41 on each arm provide for centring the moving coil 16. To the shaft 36 is fastened a scale arm 37 carrying a weight 39 by which a coarse adjustment of the tension in the members 19, 20, 21 is effected. Fine adjustment is carried out by means of a spring balance 40 attached to one end of a cord which is fastened at its other end to the periphery of a disc 38 carried by the shaft 36. The coil 16 is driven by alternating current supplied to the bridge from a source 42, preferably through a filter 51. The tension in the members 19, 20, 21 is varied simultaneously with the resistance 13 until balance is obtained, is indicated by absence of tone in the headphones 52. The coil 16 is then vibrating in resonance with the alternating current supplied to it. A piece of apparatus of which the " mechanical impedance " is to be determined is then attached to the pin 25 and the bridge is again balanced by varying the tension of the wires 19, 20, 21 and the value of the resistance 13, so that the coil is again vibrating in resonance with the driving current. The difference between the values of the tension in the members 19, 20, 21 is a measure of the " mechanical reactance" of the piece of apparatus, and the difference in the readings of the resistance 13 is a measure of the " mechanical resistance," from which quantities the " mechanical impedance " may be computed. Specification 252,657, [Class 40 (ii), Phonographs &c.], is referred to.

Title: Improvements in or relating to a dental tool
IPC: A61C5/06
Filed: 1966-03-04
Abstract: 1,134,134. Dental instruments. DENTISTS' SUPPLY CO. OF NEW YORK. 4 March, 1966 [8 March, 1965; 14 Feb., 1966], No. 9671/66. Heading A5R. [Also in Division B1] A dental amalgam applicator comprises a rotatable conveyor 18 arranged to move amalgam from a reservoir 12 to a discharge tube 16, the conveyorbeing provided with a spiral formation to move the amalgam between the conveyor and the walls of the housing 11 of the applicator, and the housing being tapered over a portion 11F so that the amalgam is squeezed as it is moved towards the discharge tube. The conveyor may be rotated through a drive shaft 22 by a conventional dental engine and a plunger 14 on the reservoir 12 may be actuated with a finger to feed the amalgam to the conveyor. A spring fitted within the tube 16 and secured to the rotatable conveyor agitates the amalgam as it moves through the discharge tube. A mercurysilver amalgam may be used and the squeezing action is said to provide an amalgam at the tube 16 having a lower mercury content than that in the reservoir 12, some mercury having been condensed out of the amalgam and either remaining within the housing 11 or leaving the applicator through suitable holes provided in the wall of the tube 16.

Title: Waveguide arrangements
IPC: G02F3/00
Filed: 1971-04-17
Abstract: 1373956 Modulating light PLESSEY CO Ltd 14 April 1972 [17 April 1971] 9757/71 Heading H4F Two members having a common interface defining a potential wave guiding channel and formed, e.g. of KDP, are oriented relative to one another so that when a common electric field applied thereto is varied, the refractive indices presented to a beam of light having a predetermined polarization are changed in opposite senses in dependence upon the sense in which the electric field is varied, so that light travelling along said channel is either confined thereto or dispersed. Thus in Fig. 2, a cylindrical portion 6 of a block 4 of electro-optic material is rotated by 180 degrees about its longitudinal axis. Application of a field via electrodes 10a and 10b produces by way of the Pockel (linear electrooptic) effect opposite variations of refractive index in portions 6 and 8, the senses of the variations being determined by the polarity of the applied field and the plane of polarization of light which is being considered. For a field of one polarity, portion 6 will act as a selective guide for a particular plane polarized beam, and with a reversed polarity field, portion 6 will act as a selective guide for a beam of orthogonal polarization. In a modification, one portion of a block of electro-optic material is rotated by 90 degrees relative to the other portion, and one portion exhibits the quadratic (Kerr) effect and the other the linear Pockel effect. In this case the refractive indices change in opposite senses for only one polarity of applied electric field. In Fig. 4, two such portions 14, 16, of rectangular cross-section are disposed in a surface of a block 18. The central portions are parallel and closely spaced, the length and spacing being such that in the presence of an electric field of a first value, a light beam entering input A is transferred once only to portion 16 and back to portion 14 to leave at output B. With an increase in the electric field intensity, the beam is only transferred to portion 16 within the length of the central portion available and leaves at output D. Such devices may be used in combinations for performing logic functions, Figs. 5 and 6 (not shown) and for selectively passing the beam through an optical delay, Fig. 7 (not shown).

Title: Process for expressing functional insect specific toxin gene in mammalian cells
Inventor: LAI MEI-HUEI TSAI
IPC: C12N5/10
Filed: 1990-08-10
Abstract: The present invention discloses a novel method for the production of a properly folded, functional insect-specific insect toxin protein in eucaryotic cells. The expression of the functional protein is achieved by the fusion of the DNA sequence encoding the structural gene product to a heterologous mammalian signal peptide. In the preferred embodiment of the invention described herein, the DNA sequence encoding the insect toxin of the scorpion Androctonus australis is joined directly to the DNA sequence encoding the human interleukin-2 signal peptide. This hybrid gene is incorporated into a eucaryotic cloning vector incorporating a selectable marker. Colonies of transformed cells identified via the selectable marker were subcultured and the culture media assayed for insecticidal activity. The resultant secreted protein demonstrated insecticidal activity against Aedes aegypti mosquito instar larvae while demonstrating no toxic effects in mice.

Title: Ultraviolet erasing type read-only memory element
Inventor: FURUKAWA YUUICHI
IPC: H01L29/792
Filed: 1984-01-07
Abstract: PURPOSE:To shorten the erasing time by the projection of ultraviolet rays without deteriorating a writing function by forming through-holes at a regular interval to a control gate and coating and burying the gate with an SiO2 layer in the thickness of equal size. CONSTITUTION:Single or plural rows and plural lines holes are formed to the plane of a control gate 1a, and the gate 1a is coated and buried with an SiO2 layer in the thickness of equal size. Consequently, SiO2 intrudes into the holes of the gate 1a and slight indentations are formed to the upper surface of the SiO2 film in sections just above the holes. The indentations function as the diffusion of incident ultraviolet rays because they serve as concave lenses, and ultraviolet rays reach to the upper section of a floating gate 2 while they reflect to the inner surfaces of the hole sections in the gate 1a. Ultraviolet rays are spread within a range wider than the hole diameter of the gate 1a, and the gate 2 is irradiated with ultraviolet rays. According to such constitution, the erasing time can be shortened because the effect of ultraviolet-ray projection to the gate 2 can be increased without deteriorating the control function of the gate 1a.
